A truck should ride like a truck, not a plush LINCOLN Towncar.
Put the air pressure in them recommended by your tire technician. They will probably ride good and wear good.
I myself ran Load range E rated 245 75R 16's on my 99 F 150 x-cab 4x4 and I ran the pressures at 45 psi all the way around(most of the time). I will admit the ride is harsher than the the wimpy load range C tires that came on the truck, but it sure did corner better and if I put a respectable load on it I could run the tire pressures up to 70 psi to handle the load.
Just my two cents, have since sold the F150 truck. Still have the old 3/4 ton yet. With the live axle front end and the ride of a lumber wagon. But it rides like a dream with about 1000 pounds in the bed. Just gets the springs limbered up.

Interesting thread. When I weighed my empty F-150 last week, the rear axle carried a significantly lower weight than the front. That means the rear tires are carrying less weight, too and might have a different profile than the front tires. Today when I had the tires rotated, the front tires had about 2/32 inch shallower tread than the rear. I wonder if the heavier weight on the front tires is the reason for that because the truck goes many more miles straight than it does turning (I think the alignment is good on the front tires.) Maybe the next pricey option for a pickup will be a system to inflate and deflate the tires to keep a constant pressure and a constant area of tread contact with the road, no matter what the load or the temperature of the air inside the tires.

fortunately for automobiles (not bikes) if you rotate them regularly it shouldnt be toomuch of a problem.
and when it comes to trucks - thats also the reason why i will run 38psi up front and 32 out back...less load.
